It's pretty straight forward though. If you have problems with it or if it looks too difficult for you to use then you can also find some consumer programs like Apple Garage Band or Sony's basic level of Acid (Acid Pro is it's professional version). I think you can pick up both of those last two programs for between $75-100.

Sony's Acid may be a lot easier for you to use dude because it has non-destructive editing to where you can cut the clips but then pull them back out again by click+drag if you fucked up. It's a basic program that's pretty good for people new to audio editing. You can also download a trial of that from http://www.sonycreativesoftware.com/products/product.asp?pid=443

Seconded for Audacity. I love it. Small enough to throw on my thumb drive... and I use it at work to isolate audio of our anchors flubbing lines... Gonna make a soundboard of them... (Like my own joke-bombing sound effect Instant Replay machine.)

Only thing I don't like about Audacity is that the waveform is like a tenth of a second behind the actual audio when you play something. But for what it does and the price (free!) I can totally deal with it. It's not a problem at all.
